Example 1

Referring to fig. 1-3, the present invention discloses a bicycle stand, which comprises a bottom frame 100, a stand 200 and a hook 300.

The base frame 100 is placed on the ground. The invention discloses an underframe 100 with light dead weight and simple structure, which comprises a cross beam 110, two parallel longitudinal beams 120, a first supporting leg 130, a second supporting leg 140 and an anti-roll bar 150. The cross member 110 and the two parallel longitudinal members 120 are arranged in a T-shape so that the bottom frame 100 can be stably placed, and the anti-toppling bar 150 is arranged on the other side of the cross member 110 opposite to the two parallel longitudinal members 120 in order to prevent the bicycle from toppling when the bicycle is mounted.

The first leg 130 and the second leg 140 are respectively connected to two ends of the two parallel longitudinal beams 120 to form a wheel groove for accommodating the rear wheel. The first leg 130 and the second leg 140 are respectively provided with an arc-shaped groove 131 and an arc-shaped groove 141 corresponding to the tire edge. To meet the requirements of wide tires and narrow tires, the arc-shaped groove 141 is taken as an example and includes a wide groove 1411 and a narrow groove 1412 disposed at the center of the wide groove 1411. For storage, the cross member 110, the two parallel longitudinal members 120, the first leg 130, the second leg 140 and the anti-roll bar 150 are detachably connected.

The stand 200 includes a fixed end 210 and a telescopic end 220. The fixing end 210 is tubular, the fixing end 210 is fixed on the base frame 100, and the telescopic end 220 is inserted into the fixing end 210 and can adjust the extending length.

Specifically, a plurality of first positioning holes 211 are arranged on the tube wall of the fixed end 210 along the length direction, and a first elastic positioning pin 221 adapted to the first positioning holes 211 is disposed in the telescopic end 220. Thus, the extension length of the telescopic end 220 can be adjusted by positioning the first elastic positioning pin 221 on different first positioning holes 211, and the height of the stand 200 can be changed.

More specifically, in this embodiment, the telescopic end 220 is also tubular, the first elastic positioning pin 221 includes a V-shaped spring 2211 and a first pin 2212, one end of the V-shaped spring 2211 is fixed in the inner cavity of the telescopic end 220, the other end is connected to the first pin 2212, and the first pin 2212 extends from the tube wall of the telescopic end 220.

In order to prevent the telescopic end 220 from being pulled out of the fixing end 210, the stand 200 further includes an inter-pipe bushing 230, and the inter-pipe bushing 230 is inserted and fixed in the insertion end of the fixing end 210. The telescopic end 220 is inserted into the inter-pipe bushing 230, and an anti-slip buckle 222 is formed at a tail portion of an insertion end thereof to be caught on an insertion end edge of the inter-pipe bushing 230 after the inter-pipe bushing 230 is inserted. Thus, when the telescopic end 220 is pulled to the position of the nozzle of the fixed end 210, the anti-slip catch 222 abuts against the edge of the insertion end of the inter-tube bushing 230, preventing the telescopic end 220 from being pulled off the fixed end 210.

The inter-pipe bush 230 is formed with a click pin 240, and the wall of the fixed end 210 is formed with a click hole 212 corresponding to the click pin 240, so that the inter-pipe bush 230 is inserted into the insertion end of the fixed end 210, and the click pin 240 is inserted into the click hole 212 to complete the click. To facilitate insertion, a guide slope 241 is formed at the top of the latch 240 in the insertion direction.

In this embodiment, the tail of the telescopic end 220 is flanged outward to form the anti-falling buckle 222, so that the process is simple and reliable.

A hanger 300 is attached to the telescoping end 220 to suspend the front wheel. Thus, by adjusting the height of the stand 200, the front wheel of the bicycle is hung on the hook 300 and the rear wheel is placed in the wheel groove after adjustment, thereby completing the vertical hanging of the bicycle.

Example 2

Embodiment 2 is different from embodiment 1 in that the length of the wheel groove is adjustable, and a false touch prevention structure is provided for the stand 200.

Referring to fig. 4 and 5, in the present embodiment, the second supporting leg 140 is connected to the two parallel longitudinal beams 120 in a sliding manner, a plurality of second positioning holes 121 are arranged at the bottom of at least one longitudinal beam 120 along the length direction thereof, and the second supporting leg 140 is provided with a second elastic positioning pin 143 corresponding to the second positioning holes 121, so that the effective length of the wheel slot can be adjusted by the cooperation of the second elastic positioning pin 143 and the second positioning holes 121, and further, the wheel slot can be matched with the stand 200, so as to adapt to bicycles with different wheel diameters, and enable the stand posture thereof to be adjustable.

Specifically, the second elastic positioning pin 143 includes a second pin body 144, a spring 145, and a pull ring 146. A seat plate 142 is formed in the second leg 140, a pin hole is formed in the seat plate 142, the second pin body 144 is inserted into the pin hole, an upper stopper 1441 and a lower stopper 1442 are formed above and below the pin hole, the spring 145 is sleeved on the second pin body 144 and is located between the upper stopper 1441 and the seat plate 142, and the pull ring 146 is connected to the lower end of the second pin body 144. Thus, when the length of the wheel groove needs to be adjusted, the pull ring 146 is hooked downwards, so that the second pin body 144 is pulled downwards to separate from the second positioning hole 121 against the elastic force of the spring 145, and when the second support leg 140 is pushed to the preset position, the pull ring 146 is loosened, so that the second pin body 144 is embedded and clamped in the corresponding second positioning hole 121, and the length adjustment of the wheel groove is completed.

In this embodiment, the lower detent 1442 is implemented by a protruding ring of the second pin body 144, and the upper detent 1441 is implemented by a plug inserted radially (in an interference fit) into the second pin body 144.

In order to prevent the first elastic positioning pin 221 from being touched by mistake (e.g., when a child transfers his/her skin to press) when the hook 300 is under a load (i.e., a bicycle is hung), which may cause a fall of the bicycle to cause a damage to the bicycle body or a personal injury, the embodiment provides an anti-touch structure on the stand 200.

Specifically, referring to fig. 4, 5 and 6, a hinge bracket 250 is disposed on the telescopic end 220, the hook 300 is hinged in the hinge bracket 250 in a hinge manner, one end of the hook 300 extends into the telescopic end 220 and is prevented from being tilted up by a limit structure, and a rope hanging hole 310 is formed at the extending end. The opening of the V-shaped reed 2211 faces downwards, and the top center of the V-shaped reed 2211 forms a rope passing hole 22111; the cavity of the stand 200 is further provided with a weight block 260, the weight block 260 is in a circular truncated cone shape with a small top and a big bottom, and the weight block is suspended on the rope hanging hole 310 after passing through the rope passing hole 22111 through the steel wire rope 270.

Thus, when the end of the hook 300 is unloaded, the weight block 260 overcomes the weight of the hook 300 and moves downward (at this time, the hook end of the hook 300 tilts upward, and the extending end swings downward), and the weight block 260 leaves the inner end of the first pin 2212 or the opening end of the V-shaped reed 2211, so that the first pin 2212 can retract inward, and at this time, the first pin 2212 can be flexibly pressed down to adjust the height of the stand 200. When the end of the hook 300 is hung on a bicycle, the hook end of the hook 300 is pressed downwards, at the moment, the wire rope 270 lifts the balancing weight 260 to enable the circumferential surface of the balancing weight 260 to abut against the inner end of the first pin 2212 or extend into the opening end of the V-shaped reed 2211 to prevent the first pin 2212 from retracting inwards, at the moment, the inner end of the first pin 2212 is prevented, or the opening end of the V-shaped reed 2211 is prevented from deforming, at the moment, the first pin 2212 cannot be pressed, and the problem of mistaken touch is solved.

Referring to fig. 6 and 7, in order to prevent the extending end of the hook 300 from being tilted upward to meet the requirement of mounting, the limiting structure may be a limiting bolt 280 locked on the sidewall of the telescopic end 220. Referring to fig. 8, the limiting structure may also be an extending end of the hook 300 itself, i.e. the end surface of the extending end is a plane and abuts against the tube wall of the telescopic end 220 when extending, and at this time, the upper half of the end surface of the extending end should be in semi-arc transition so that it can swing downwards. In addition, the limiting structure can also be the upper edge of the opening on the telescopic end 220 for the hook 300 to extend into.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
